Using terahertz scanning tunneling microscopy, researchers demonstrate that atomic-scale defects in semiconducting 2H- modulate the local coupling to THz fields via band bending, thereby enabling the selective excitation and control of otherwise forbidden coherent phonon modes at the nanoscale.
This paper challenges the prevailing belief that half-integer thermal conductance is an unambiguous signature of non-Abelian Majorana modes by demonstrating through theory and experiment that such values can robustly arise in Abelian bilayer graphene systems due to mundane equilibration dynamics between distinct integer quantum Hall states.
This study elucidates the mechanism of three-magnon splitting in synthetic antiferromagnet spin wave conduits, revealing that low-order optical spin waves decay into parallel channels of non-degenerate acoustic doublets with standing wave characteristics, a finding with significant implications for nonlinear microwave signal processing applications.
Using in situ scanning electron microscopy and molecular dynamics simulations, this study demonstrates that graphene etching within the van der Waals gap on platinum is primarily limited by mass transport, yet once overcome, the confined space acts as an effective nanoreactor that enables unique reaction pathways and enhanced rates for molecules like O2, H2, and CO.
This study demonstrates that Fe adatoms on 2H-NbSe undergo spin quenching via -level hybridization to form stable non-magnetic dimers, resulting in distinct ground states for even and odd chains where odd chains host a switchable end-state magnetic atom, thereby highlighting the potential for engineering topological systems through controlled dimerization.
This study demonstrates that yttrium scandium gallium aluminum garnet (YSGAG) serves as an ideal diamagnetic substrate for yttrium iron garnet (YIG) films in quantum magnonics by eliminating the low-temperature magnetic damping caused by conventional gadolinium gallium garnet (GGG) substrates, thereby preserving exceptionally low damping from room temperature down to 30 mK.
This topical review theoretically analyzes the resonance fluorescence of acoustically modulated single-photon emitters using Floquet theory to explain complex spectral features arising from double dressing, ultimately identifying surface and bulk acoustic waves interfaced with quantum dots as the most promising platforms for acousto-optical Floquet engineering.
By utilizing ionic liquid gating on homoepitaxial SrTiO thin films, researchers achieved a superconducting transition temperature of up to 503 mK and observed consistent BCS scaling and paraconductivity behavior, marking a significant improvement over similar systems on single-crystal substrates.
This pedagogical lecture note provides a detailed many-body perspective on classifying free fermionic topological phases, covering symmetry-protected topological insulators, symmetry-free topological superconductors, and the stability of 1D phases under interactions.
This study demonstrates that nano-patterned semiconductor interfaces can create artificial hexagonal boron nitride with topological valley Hall states that exhibit remarkable resilience against experimental disorder, offering a promising platform for low-dissipation valleytronic applications.
